Aneuploidy selects for the acquisition of driver genes in breast cancer

Nature, Published online: 08 July 2026; doi:10.1038/s41586-026-10752-9

Screening of chromosome arm-level aneuploidies uncovers that these alterations select for specific basal-like breast cancer driver genes, including PLGRKT, an oncogene whose tumour-promoting activity is associated with highly stress-resistant mitochondria and enhanced detoxification of reactive oxygen species.

Mitigation of hydrogen crossover in liquid alkaline water electrolysers using gas recombination catalysts

Nature Energy, Published online: 26 June 2026; doi:10.1038/s41560-026-02094-7

Alkaline water electrolysers are being optimized for higher performance, but measures such as advanced electrodes or thinner separators can increase hydrogen crossover and safety risks. Here the authors analyse crossover behaviour and show that a gas recombination catalyst cuts crossover by 95% without affecting electrolyser performance.

Have You Bought a Tesla Recently? We Want to Hear From You.

Tesla sales are rebounding in Europe even though many people have negative feelings about Elon Musk, the company’s chief executive. We want to know why.
